3D Instruments

3D Instruments has provided rugged and reliable pressure measurement instrumentation for virtually every industry around the world. It created the “Direct Drive Technology” concept, which couples the bourdon tube directly to the shaft-pointer. This streamlines the design and reduces the number of moving parts from approximately twelve down to one, making the Precision Caisson Gauge, the Pneumo Depth Gauge and the Accu-Cal Digital Precision Test Gauge very low maintenance.

The 3D Instruments 2564 Series Precision Caisson Gauge is used inside a hyperbaric chamber and reads ambient chamber pressure. Accuracy is maintained for both increasing and decreasing pressures and always indicates true gauge pressure and/or a simulated depth in a chamber.

The 3DI CPP30 Pneumatic Hand Pump is used to generate pressure for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure tests may be carried out in laboratories, workshops or on site at the measuring point.
